Sometimes there's a bunch of junk in the binary that isn't used for anything. Often it's there to make things line up at the start of a page boundary. This adds a ".junk" directive that tells the disassembler that it can safely disregard the contents of a region. If the region ends on a power-of-two boundary, an alignment value can be specified. The assembly source generators will output an alignment directive when possible, a .fill directive when appropriate, and a .dense directive when all else fails. Because we're required to regenerate the original data file, it's not always possible to avoid generating a hex dump.
